[0054] Please continue reading Figure 5 The utility model also proposes a crane-type cradle five-axis machining center, which includes the crane-type cradle five-axis top protection mechanism mentioned in any of the above embodiments, and the detailed structure can refer to any of the above embodiments.

[0055] Please combine Figures 1 to 5 See also Figure 6 , Figure 6 This is a structural schematic diagram of another embodiment of the five-axis top protection mechanism of the overhead crane type cradle of the utility model. In order to facilitate the understanding of the five-axis top protection mechanism of the overhead crane type cradle proposed by the utility model, the specific extension and contraction process of the mechanism is introduced below.

[0056] In one embodiment, if Figure 5 As shown, the current protective shed 10 is in an open state, so as to block the splashing cutting fluid and impurities during the machining process when the overhead crane type cradle five-axis machining center processes the workpiece, thereby increasing the service life of the overhead crane type cradle five-axis machining center.

[0057] Further, after the processing is completed, the driving assembly drives the first side 11 of the protective shed 10 to move in direction B through the first connecting member 30.

[0058] Furthermore, in order to avoid affecting the opening and closing of the protective door 80 of the overhead crane type cradle five-axis machining center, the driving assembly drives the fully retracted protective shed 10 to move in the opposite direction of direction B until the fully retracted protective shed 10 moves to the corresponding position, thereby realizing the closing of the protective shed 10. Figure 6 shown.

[0059] In another implementation scenario, Figure 6 As shown, the current protective shed 10 is in a closed state. When the workpiece in the processing area needs to be processed, the driving component preferentially drives the protective shed 10 in the closed state to move in direction B to the side close to the protective door 80. At this time, the second side 12 of the protective shed 10 is adsorbed on the surface of the overhead crane cradle five-axis machining center close to the protective door 80 through the adsorption component 50.

[0060] Furthermore, the air claw 210 in the clamping device 21 changes from a closed state to an open state, and the driving component drives the first side surface 11 of the protective shed 10 to move in the opposite direction of direction B until the first side surface 11 moves to a corresponding position, so as to realize the opening of the protective shed 10 and cover the top of the processing area.
